Getting Ready

1-2

As you unpack your terminal, make sure you received everything shown below. If anything is missing or visibly damaged, contact the dealer from whom you purchased the terminal.

Power Cord

The keyboard cable and the power cord come with your terminal. You'll also need an RS-232C interface cable (fitted with a female 25-pin connector on one end) to connect the terminal to your computer. To connect a serial-type printer directly to your terminal, you'll need a second RS-232C interface cable. These cables can be purchased from your dealer.

The terminal should be located in an area

• Near a grounded, three-pronged power outlet.

• In an area with indirect lighting, and away from windows, if possible. Nearby windows should be on either side of the terminal.

• Large enough to allow three inches of space around the terminal for ventilation.

Chapter 1

Connecting the Terminal to a Computer

To connect the terminal to your computer

1. Press the bottom half of the power switch on the front of the terminal's base to the off position.

2. Plug the coiled cable into the socket labeled KYBD on the back of the terminal and into the keyboard.

4. The power requirements shown on the label on the back of the terminal should match the voltage in your area. If not, return your terminal to the factory (or contact your distributor) to change the setting.

Voltage Label ---nmm::-

Chapter 1

5. Plug the pronged end of the power cord into a three-pronged (in the U.S.), grounded power outlet (or use an adapter for a two-pronged outlet). However, if you only have a two-pronged power outlet, be sure to ground the outlet by attaching the adapter's pigtail to the faceplate screw.

6. Locate your computer's interface cable. It should be an EIA-standard RS-232C or RS-423 cable with a female 25-pin connector on at least one end. If you're connecting a computer configured for current loop (such as a DEC), the interface cable will be an 8-pin, male 20mA connector (MATE-N-LOK) .

• Note-Not every computer has the same configuration on its RS-232C port. If the pin connector on the RS-232C cable isn't configured to meet the requirements of the computer and the terminal, they won't work as expected (or may not work at all). The pin assignments of the terminal's ports are listed in Appendix B. If the connection pins differ, you should contact the systems analyst for your computer to see about reconfiguration.


1-6

7. Connect the computer interface cable to the terminal's COMM port and to your computer's RS-232C port. If your computer is configured for current loop, connect the 8-pin cable to the terminal's 20mA port and the computer's interface port. The 20mA port is pin-compatible with DEC computers. See Appendix B for pin assignments of the 20mA port.

8. With an l/s-inch, flat-blade screwdriver, tighten the screws on both sides of each connector.

Chapter 1

Connecting a Modem You can connect a modem to the terminal so it communicates over telephone lines with another computer .

• Note-If the pin assignments required by your modem differ from those needed by your computer, you'll need an RS-232C interface cable especially configured for your modem. Your modem may have its own cable. Refer to your modem's reference manual for details.

1. Attach the female end of the 25-pin RS-232C interface cable to the COMM port on the back of the terminal.

Terminal COMM Port

2. Attach the other end of the cable to your modem's RS-232C connector.

3. Follow the instructions in your modem's manual to connect the modem to your telephone.

4. With an Vs-inch, flat-blade screwdriver, tighten the screws on both sides of each connector to secure the interface.

Appendix B lists the pin connections for the Hayes Smartmodem.


Connecting a Printer

1-8

If your software supports a printer connected to a terminal, you can connect a serial printer directly to the terminal. You'll need an RS-232C interface cable with a 9-pin, D-shaped female connector on one end.

1. Plug the printer interface cable into the PR port on the back of the terminal.

2. With an \Is-inch, flat-blade screwdriver, tighten the screws on both sides of each connector until secure.

3. Attach the other end of the interface cable to the RS-232C port on the printer .

• Note-The TEST port is for manufacturing purposes only. Do not use this port.

Appendix B lists typical pin connections for a printer.

Chapter 1

Turning on the Terminal After the terminal is properly installed, turn it on by pressing the top half of the terminal's power switch. Listen for an immediate beep indicating that it has received power.

Whenever you turn the terminal on, it automatically runs a five-second self-test. If the terminal has recently been on and the cathode ray tube (CRT) is warm, the screen flashes several display patterns as the self-test runs.

If the terminal encounters a problem during the self-test, a beep sounds and an error code appears in the bottom right-hand corner of the screen. You can't operate the terminal if certain error message are shown; it may need to be serviced by a qualified technician .

• Note-If you see an X or Y in the bottom right corner of the screen, see the Troubleshooting chapter.

To reset the terminal so that it will rerun its self-test, press the SHIFT key, CTRL key, and SETUP (F3) key simultaneously.

When the cursor is in the upper left corner of the screen, the terminal has passed all of its tests and is ready for operation.

The next thing to appear on the screen is the message line. LINE, LOCL, ECHO, or BLCK appear at the top left part of the screen. Later you may see messages about the terminal (called terminal status messages) above the left half of the line. Messages from the computer may appear above the right half of the line.


Adjusting the Terminal

Completing Installation

1-10

Adjust your terminal so that the center of the screen is slightly below your eye level. Swivel the screen sideways and up and down until you find the most comfortable angle.

If you want the keyboard tilted slightly, turn it over and pull out the hinged bars. Typing will be more comfortable if the keyboard is at or below your elbow height.

Adjust the intensity of the screen display by turning the brightness control thumbwheellocated at the lower front right corner of the terminal.

Now you've completed the physical installation of the terminal. Before the terminal and computer can communicate, however, you must check the terminal's setup parameters. This is explained in detail in Chapter 2.

Chapter 1

2 Configuring the Terminal This chapter discusses the setup mode, which includes the keyboard, communication, printer, and send levels.

Entering Setup Mode 2-2 Describes the setup mode and how to enter it

Changing the Setup Parameters 2-4 Describes the setup directory and its function; and each setup level

Leaving Setup Mode 2-27 Describes how to exit the setup mode

Chapter 2 2-1

Introduction

Entering Setup Mode

2-2

The terminal and computer must have a common language to communicate. This language is determined by a set of variables called parameters. You can change the values of your terminal's parameters in the setup mode to enable the terminal to communicate with many manufacturers' computers.

The way a terminal's parameters are set make up its configuration. The configuration of your terminal and computer (or other device) must match.

Your terminal has a set of default values. Since these default values may not exactly match the device you want to attach, you may need to change some of these values.

In setup mode, you can also change optional parameters, such as the number of columns displayed on the screen or your cursor attributes, as well as program a set of user-defined function keys to perform desired functions.

Enter setup mode by pressing the SETUP (F3) key. During setup mode, the cursor temporarily disappears, but reappears when the terminal is in its normal mode. The information you enter remains frozen on the screen and cannot be altered .

... Caution-Do not enter setup mode while data is being transmitted between the terminal and the computer. The terminal cannot receive data during setup mode.

A row of boxes (called fields) appear at the top of the screen in setup mode. Each field defines the function of a special key. The fields on the bottom of the screen contain text. These fields make up the setup line and display the parameters you can define for the terminal. See the following figure.

The highlighted field on the setup line is the active field, or the field whose values you can change. Activate desired fields by pressing the. or ~ cursor key.

The setup line has 44 levels arranged in the order shown in Table 2-1. Each setup level displays a different set of parameters. Table 2-1 lists the setup levels and describes the features you can change in each.

The first time setup mode is entered, default values appear. Depending on your requirements, you'll probably need to change some of these values.

You can make either device-dependent or optional changes. Optional features, such as a blinking cursor, are a matter of preference and can be changed according to your needs. Device-dependent features must be set according to the requirements of your attached device (modem, printer, etc.).

Explanation

The code programmed into keys F6 through F20 (unshifted) is sent to the computer, unless the terminal is in local mode.

The code programmed into keys F6 through F20 (unshifted) is processed locally by the terminal.

Data generated by programmed function keys is transmitted at a maximum rate of 60 characters per second (cps), regardless of baud rate.

Programmed function key data is transmitted at a maximum rate of 150 cps.

Programmed function key data is transmitted as fast as possible.

Send line and screen commands transmit all characters.

Send commands transmit only characters specified as erasable; a record separator character is transmitted in place of one or more contiguous nonerasable character(s).

Send screen operations transmit the entire screen.

Send screen operations transmit only active scroll region.

No character is sent after a send screen operation.

A form feed (FF) is sent after a send screen operation.


2-22

The Answerback Setup (Level 12)

You can ask the terminal to send an answerback message to the computer before it can log on or access an application. The answerback message may act like a password and can be sent automatically by the terminal, or the message can be sent manually from the keyboard. For purposes of confidentiality, you can conceal this password.

The answerback message is transmitted to the computer in the following cases:

• The computer receives the ENQ character and the terminal is in VT200, VT100, or VT52 mode .

• You press the BREAK (F5) key with the CTRL and SHIFT keys.

To define the answerback message:

l. Press the SETUP key (F3) to enter setup mode and display the setup directory.

2. Press the ~ key until the Tabs field in the bottom line is highlighted.

3. Press the spacebar or ENTER key to enter the Tabs setup level.

4. Press the. key to enter the Answerback setup level.

5. Press the <XI key to clear the old message, then type the new message (up to 30 characters).

To conceal the answerback message and keep it from being displayed press the REMOVE key at any time on this level. The answerback message is replaced by the word <CONCEALED> and cannot be redisplayed unless you redefine it.

The Tabs Setup (Level 13)

By default, tab stops are set every eight columns across the screen, beginning with column nine. When you enter the Tabs setup level, the tab stops (indicated by the letter T) are on a line displayed under the setup line at the bottom of the screen. The tab stops aren't numbered, but you can determine the placement of each by moving the cursor across the line and reading the column number displayed in the message field at the top of the screen.

You can clear and set tab stops anywhere within the margins from the Tabs setup level:

1. Press the SETUP key (F3) to display the setup directory.

2. Highlight the Tab field and press the spacebar or ENTER key to enter the Tabs setup level.

3. With the cursor on the tab line, position tab stops where you want.

• To move the cursor across the line, press the ~ or ... cursor keys.

• To clear all tab stops, press the <ZI key.

• To clear an individual tab stop at the cursor position, press the spacebar.

• To set an individual tab stop at the cursor position, press the T key.

• To alternately set or clear a tab at the cursor position, press the ENTER key.

• To restore all the default tabs, press the TAB key.

The Function Key Setup (Levels 14-43)

The keyboard's function keys can transmit multiple characters with one keystroke. F6 through F20, including HELP and DO, are programmable; you can assign them any number of possible functions.

If the unshifted function keys have never been programmed, they transmit a set of standard default codes. The WY-85 Programmer's Guide lists those codes. The shifted function keys are initially blank and perform no function until programmed.

~ Caution-Applications that require default values for the unshifted function keys may not run properly if you redefine these keys.

To program a function key:

• Note - If the Key Lock parameter (first Keyboard level) is set to On, you won't be able to program the shifted function keys.

1. Press SETUP (F3) to put the terminal in setup mode and display the setup directory.


2-24

2. Highlight Function Keys on the setup line and press the spacebar or ENTER key to enter the first Function Key setup level (level 14).

3. Press the ~ key until you reach the level containing your key; or press the function key you want to change. Shifted function keys (F6 S through F20 S) are programmed in levels 14 through 28. Unshifted function keys (F6 U through F20 U) are in levels 29 through 43.

4. The normal bottom setup line is replaced with a highlighted field, such as

I F1 5

To program the key, just type the characters you want transmitted. You may enter as many characters as there is space in the field, which is generally 80 characters in 80-column mode and 127 characters in the 132-column mode.

To enter a carriage return (CR) code in the sequence, hold down the CTRL key while pressing M (or RETURN). A carriage return counts as one character.

If you make a mistake, press the Q] key to erase the entire line or press the .... key to erase one character.

5. To display other function key levels, press the A and ~ keys, or press the desired function key.

6. To stop programming function keys and display the setup directory, press SETUP (F3) or another function key.

For example, to program F7 (shifted) to send the code sequence DIR<CR> (directory-carriage return), follow these steps:

1. Press the SETUP key (F3).

2. Highlight Function Key on the setup line and press the spacebar or ENTER key.

3. Press the ~ key once or press the F7 key with SHIFT held down.

4. Type DrR

5. Press the M key while holding down CTRL, or press RETURN to send a carriage return.

6. To return to the setup directory, press the SETUP key.

Chapter 2

Leaving Setup Mode

To display the disk's directory, you can just press F7 (or whatever key you've defined), instead of having to type in the command

DIR<CR>

• Note - Your computer's response to a transmitted code depends on the program you're running at the time. Different programs may interpret the same code differently.

You can define the function keys as a group to act as either local or remote keys. Local keys are processed at the terminal only; remote keys transmit characters to the computer first. See "Keyboard Two Setup Level" in this chapter.

There are 400 characters available for all function keys. The first 134 characters are saved in nonvolatile memory; characters beyond that are erased when you turn off the terminal. Those 134 characters saved are indicated by full-intensity characters in the function key definition field; those characters erased will appear dim.

The 134 nonvolatile characters are allocated to the first function keys in sequential order (F6 S through F20 S, then F6 U through F20 U). If you redefine the programs of higher priority keys, be aware that you may alter the volatility of characters in lower priority keys. For more information see the WY-85 Programmer~ Guide.

When you exit setup mode, you have the choice of saving or not saving the changes you made. Changes you make but don't save still take effect after you exit setup mode but only stay in effect until you turn the terminal off. To exit setup mode and save changes:

1. Press SETUP (F3) to display the setup directory.

2. Select the Save function and press the spacebar or ENTER key. The screen blanks for two to five seconds.

3. You automatically exit setup mode after a save operation.

All changes, including new function key definitions, tab stops, and answerback messages (the first 134 characters only), are saved and will still be in effect after the next power-on.


2-26

To exit the setup mode without saving changes:

1. Press the SETUP key (F3).

2. Select EXIT and press the spacebar or ENTER key, or press the SETUP key again.

The terminal operates with the changed setup parameter selections. When the terminal is turned on again, the setup parameters will be what they were before you made these changes.

Keyboard Description

3-2

The keyboard consists of a main keypad, an editing keypad, an auxiliary keypad, and a row of 20 function keys. The main keypad contains the standard alphanumeric keys of letters, numbers, and symbols usually associated with those on a typewriter keyboard. The editing keypad contains cursor movement keys and special editing keys. The auxiliary keypad contains four PF keys and a standard numeric keypad, which is helpful in heavily numeric text such as that used in accounting records. Function keys F 1 through F5 perform predefined local functions. Function keys F6 through F20 either generate predefined codes or they may be reprogrammed to generate user-defined codes (see Chapter 2).

Table 3-1 describes the special keys of the main keypad. Table 3-2 describes the special keys of the editing keypad. Table 3-3 describes the PF keys and the function keys.

Keys are either local or remote. Local keys cause specific functions to occur, generally without communication to the computer. Remote keys send data to the computer (if the terminal is in full-duplex online mode). This data is interpreted by the computer, which then performs a specific action based on this data.

Key Description

COMPOSE CHARACTER

CTRL

LOCK

In VT200 mode, this allows you to compose multinational (European) characters not found on the keyboard. In VT100 or VT52 modes, pressing this key simultaneously with another key causes that character to be modified as with the META key found on other terminals. See "Composing Characters" later in this chapter.

Pressed simultaneously with another key, CTRL generates a control code. Pressing CTRL by itself has no effect. Normally undisplayed, control codes cause the terminal and! or program to take special action. Press CTRL with SHIFT and SETUP (F3) simultaneously to reset the terminal.

Initiates caps lock, shift lock, or reverse shift mode, depending on the selection made for the Lock setup parameter (first Keyboard level, Chapter 2).

When Lock is set to CAPS, all alphabetic keys typed appear as uppercase; number and symbol kt"ys are unaffected.

When Lock is set to SHIFT, letters are uppercase, and numeric and symbol keys show their shifted character.

When Lock is set to REV, the sense of the SHIFT key is reversed as it applies to alphabetic keys. In other words, pressing an alphabetic key simultaneously with the SHIFT keY, when the terminal is in the reverse lock mode, generates a lowercase character. Pressing an alphabetic key with the SHIFT key up generates uppercase characters. Number and symbol keys are unaffected.

When the terminal is in either caps lock, shift lock, or reverse shift mode. LOCK appears on the status line. Pressing LOCK toggles the terminal in and out of these modes. You can press the SHIFT key to exit the shift lock mode.

Additional Features

3-10

Scrolling Speed You can set the general scrolling speed with the Scroll parameter (first Display setup level, see Chapter 2). In addition, you can temporarily alter scrolling speed by pressing CTRL and .. to speed up scrolling, and SHIFT with CTRL and ~ to slow down scrolling. This procedure alters the value of the Scroll parameter, but does not save the change in nonvolatile memory.

Keyclick

The keyboard has an optional keydick feature that makes a muted beep each time you press a key. Switch this feature on and off by setting the Keydick parameter (Keyboard one setup level). You can also switch it on and off by pressing CTRL and ENTER. This procedure alters the values of the Keydick parameter but does not save the change in nonvolatile memory.

Graphics Characters The terminal has several special graphics character sets in addition to its standard characters. However, you can use these additional character sets only with a graphics program that was specially written for them. See the WY-85 Programmer's Guide for details.

Compose Characters In addition to the standard ASCII character set, you can compose up to 81 multinational (European) characters not found on the keyboard when you are in VT200 7-bit or 8-bit modes. The WY-85 Programmer's Guide lists the compose sequences you can type to create new characters.

To compose a new character:

l. Press COMPOSE CHARACTER. COMP appears on the status line at the top of the screen.

2. Type the keys required to create the desired character (in the order indicated). Each compose sequence consists of two characters. For example, /' creates a raised and centered dot (').

3. When a sequence is entered, the character is sent to your program and COMP disappears from the status line. If a sequence is invalid, it's aborted and, if the Warning Bell parameter (first Keyboard setup level) is on, a bell sounds.

operating Modes

Monitor Mode

You may want to inspect the code characters being sent from the computer. If the terminal is in monitor mode, these code characters appear on the screen with the normal letters. The computer doesn't act on these codes during monitor mode.

To enter monitor mode, press CTRL with the ... key, or change the Controls parameter (Display one setup level) to Display. Unless the Status Line parameter (Display two setup level) is set to off, an asterisk (*) appears next to the communication mode label on the status line. This indicates that the terminal is in monitor mode.

To exit monitor mode, press CTRL with the ... key again, and the asterisk disappears .

• Note - If the terminal is also in insert mode, an asterisk appears in place of the INS label on the status line.

The terminal provides three operating modes:

• Setup

• Online

• Local

The setup mode is only selectable from the keyboard. This mode allows you to configure the terminal or to check the previously set configuration (see Chapter 2).

The online operating mode is selectable only in the setup mode by turning off the local mode in the first General setup level. The online mode permits communication between the terminal and the computer in either full-duplex, half-duplex, or block communication modes. The communication modes determine when and where data is transmitted (sent) after you entered it at the keyboard. Half-duplex mode may be selected by the computer or by turning on the Echo field in setup (first Communication level, Chapter 2). Full-duplex mode may be selected either by the computer or by turning off Echo. Block mode may be selected either by the computer or by pressing the F4 key. These three modes also determine how the terminal interacts with the computer. Local mode is only selectable in the setup mode. The following figure illustrates how the terminal handles data in each of these communication modes.

If the terminal is in half-duplex mode and your computer expects it to be in full-duplex mode, the characters you type on the keyboard will appear twice on the screen. When the half-duplex communication mode is selected, ECHO is displayed in the status line.

Chapter 3

Full-Duplex Mode

In the online full-duplex communication mode, data entered at the keyboard is sent to the computer and data received from the computer is shown on the screen. In general, this is the normal operating mode. In this mode, LINE is displayed in the status line.

Block Mode

In the online block communication mode, data entered at the keyboard is only displayed on the terminal screen, until you decide to send the block of data to the computer or to the printer. In this mode, data is sent to the computer by pressing the SEND key, or it can be sent directly to the printer by pressing the PRINT SCREEN key. Data received by the terminal from the computer can occur at any time and will be displayed when received. When this mode is selected, BLCK is displayed in the terminal status line.

Local Mode

The local operating mode is only selectable in the setup mode. In local mode, data entered at the keyboard is shown on the display screen, but it is not sent to the computer. Furthermore, data sent by the computer is ignored by the terminal. In this mode, LOCL is displayed in the status line. You can work in the local mode to experiment with the various terminal controls without affecting the computer. Here, what you type goes only to the terminal for display on the screen.

Introduction

Symptoms and Solutions

4-2

For certain problems, the terminal may seem to malfunction when the problem is actually something you can fix yourself. The problem may be the wrong setup value, a loose cable connection, or incorrect pin connections on an interface cable. Before you place a service call, please refer to the solutions listed in this chapter .

• Warning-We are NOT suggesting that you try to fix internal problems. Don't open the terminal case unless you are a qualified service technician. When the case is open, dangerous voltages are exposed, even after the power has been turned off.

This section contains symptoms and possible solutions to problems you may encounter with your terminal. The symptom is shown in bold and suggested solutions follow.

The terminal doesn't beep when turned on .

.. Caution -The following procedure exposes you to potentially hazardous shock if you don't unplug the power cable.

1. Turn off the power switch and unplug the power cable.

2. Remove the line fuse located on the rear panel next to the power connector by inserting a small flat-head screwdriver into the fuse's slot and turning it counterclockwise.

3. If the wire inside the fuse is broken or if the glass is blackened, the fuse may be blown. Replace the fuse only with a 2 amp, 250 volt fuse if this is the case.

Chapter 4

4. Reinsert the fuse assembly in the rear panel. While pushing on the fuse assembly with the screwdriver, turn it clockwise about one-half turn. Don't force it.

5. Plug in the power cord and turn on the terminal.

Terminal beeps after turned on, but you can't see the cursor.

1. Turn the brightness thumbwheel all the way down (clockwise). See the following illustration.

2. Check the cursor field in the setup mode (Display level two) to make sure the cursor is not set to Off.

The screen goes blank while the terminal is on.

This is a normal condition when the CRT saver parameter is on. You can turn the CRT saver off in the setup mode. After 15 minutes of inactivity, the display disappears but the data is not lost. Press any key to bring back the display (SHIFT will bring back the display without altering it).

The screen doesn't respond when you press a key.

1. If WAIT appears in the terminal message line your program has locked the keyboard. To unlock it, press SETUP with SHIFT.

2. Make sure the keyboard cable connection is good.

3. If LOCK appears when you press LOCK, check the computer communications setup. See the next condition.

Troubleshooting 4-3

4-4

The computer doesn't respond when you type on the keyboard.

1. Check the interface cable connections. Is the computer interface cable connected to the COMM port? Does it have the correct connector pin assignments (see Appendix B)?

2. Make sure the status line displays LINE. If it does not turn the block mode off by pressing F4. To turn LOCL off, you must enter the setup mode, General level one. Also check the COMM port baud rate, data bit, handshake, stop bit, and parity bit selections; they should all match your computer.

When the terminal is turned on, an X or Y displays in the bottom right-hand corner of the screen.

Hold down the SETUP key to exit self-test. If the error code continues, turn the terminal off and then on again.

When the terminal is turned on, 0, 1, 2, 3, P, or Z appears in the bottom right-hand corner of the screen.

The terminal needs to be serviced by a qualified technician.

Nonsense characters (garbage) appear on the screen.

1. Match the COMM port baud rate setup parameter in the setup mode with your computer's baud rate.

2. Check the pin connections of the computer interface cable (see Appendix B).

Characters become garbled as they appear on the screen.

Make sure the selection for the stop bit, parity, and data bit setup parameters match the requirements of your computer.

All characters display double when they should be single.

Turn off the Echo communication level from the setup mode (see Chapter 2).

The function, cursor, and/or keypad keys do not work.

Make sure the selection for data bits and parity match the requirements of your computer. Most systems use 8 data bits, no parity.

line, DSR, and CTS are high. Ignored otherwise.

12 Speed Indicator SPDI (Input) If modem control mode is enabled, a high level on this line causes the terminal to transmit and receive data at the 1200 baud regardless of the speed selected in setup.

20 Data Terminal DTR (Output) When DTR Ready handshake is enabled, this line

is lowered when the terminal is not ready to receive any more data.

23 Speed Select SPDS (Output) When modem control mode is enabled, this line is lowered if the terminal's receive speed is less than 1200 baud.
